Description
The MJ Arsenal Grotto Hand Pipe is a compact, handmade borosilicate glass spoon pipe measuring 4.5" x 2.5" x 2". Named after hidden shoreline caves, it's built with a hollow-bottom base for easy cleaning and an ergonomic shape that's comfortable to hold for long sessions. It's a straightforward, well-made hand pipe at a price point that makes it easy to keep a backup on hand.

FAQs
- What is the bowl diameter? 18mm bowl diameter.
- Where is the carb? Left side of the bowl — designed for natural thumb placement when held in the right hand.
- How do I use a carb? Cover the carb with your thumb while drawing, then release it at the end of your hit to clear the smoke from the pipe.
- How do I clean it? Soak in isopropyl alcohol for 30 minutes, or fill with ISO and coarse salt, shake, and rinse. The hollow-bottom base means no trapped residue pools.
- Are the colors accurate to what's shown? Colors are handmade and will vary slightly between units. The product photos are representative but exact shades differ.
- Is this compatible with dry herb? Yes — standard dry herb hand pipe.
- How does it compare to the Cove bubbler? The Grotto is a dry hand pipe with no water filtration. The Cove bubbler adds a water chamber for smoother, cooler hits at a higher price point.

- What is a hand pipe? A hand pipe is the simplest way to smoke dry herb. Pack the bowl, cover the carb, apply heat to the bowl while inhaling, then release the carb to clear the smoke. No water, no setup required.
- How the carb works: The carb (the small hole on the side) controls airflow. Covering it while you draw builds up smoke in the pipe; releasing it at the end of your inhale flushes the remaining smoke into your lungs cleanly.
- Borosilicate glass: Higher-grade glass that handles heat better than standard glass. Significantly more durable and won't impart any flavor to the smoke.
- Bowl size matters: An 18mm bowl is a standard, medium-sized bowl. It holds enough for a couple hits in a solo session — grind your herb for more even burning.
- Cleaning keeps flavor: Even a simple hand pipe benefits from regular cleaning. Resin buildup changes the flavor and restricts airflow. Weekly ISO cleans keep it performing well.
